حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَأَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ وَعَمْرٌو النَّاقِدُ وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ عَنْ سُفْيَانَ، عَنِ الزُّهْرِيِّ، بِهَذَا الإِسْنَادِ ‏.‏ مِثْلَهُ ‏.‏ قَالَ يَحْيَى قَالَ سُفْيَانُ لاَ أَدْرِي مِنْ قَوْلِ مَنْ هُوَ يَعْنِي وَكَانَ يُؤْخَذُ بِالآخِرِ مِنْ قَوْلِ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏
